Microsoft Word: View Two Documents at Once

Word has a very neat trick that allows you to view two documents side-by-side. You can also synchronize the scrolling of the documents too so that you don’t have to change focus or jump between each one as you work through them.

Follow these steps to compare two documents:

1. Open the two documents you want to view at the same time.
2. Go to the View tab > Window command group.
3. Click View Side by Side.
4. On the Compare Side by Side window, select the document you want to compare this one to, then click OK.

The first document opens on the left and the other opens on the right. On the View tab of the left document, the synchronous scrolling button is automatically selected. Click it to turn it off and on.
